commit 4cea557a558dcc0fcecba93930a74623fd4ea7cc
Author: Colomban Wendling <ban at herbesfolles.org>
Date:   Thu May 24 18:56:49 2012 +0200

    Always use /dev/zero as the fake data source in the `sfill` wrapper
    
    Filling with pseudo-random data (/dev/urandom) is a fair bit slower and
    is not necessary since the created file is securely deleted afterwards.
